of tax fraud. the people who endured long days on a disabled cruise ship were headed home today. their ordeal in the gulf of mexico came to an end when the crippled craft pulled into port. cheers erupted from carnival cruise's "triumph" as it finally docked in mobile, alabama, late last night, five days after an engine room fire left the ship dead in the water. over the next four hours, more than 3,100 weary passengers streamed ashore. >> i mean, i'm speechless. it's just really great to finally be back in america and on land. >> sreenivasan: many took buses to new orleans to catch flights home today, while others were bused back to galveston, texas, to retrieve cars left at the ship's home port. some stopped to tell of the drama that began last sunday. >> people were slamming doors and freaking out. "the ship's on fire, the ship's on fire!" and then at that point, it kind of sunk in the reality of this is a... you know, a very serious situation. >> sreenivasan: in the days that followed, they made do with little or no power, or working toilets.
